An automatically deploying shielding apparatus, or sun shade, includes a handle and a shade portion connected by a hub. The handle extends into the hub, with the shade portion having a flexible shade joined to a first support member and a second support member. The first support member and the second support member extend into the hub, and an elastic member extends from the first support member to the second support member. The elastic member is arranged to extend through the hub and the first support member and the second support member are coupled to the hub portion with the elastic member holding the first support member and the second support member under tension at a position substantially perpendicular to the handle. A rescue cord and notch may be provided as an alternative to the elastic member, or in the event of malfunction of the elastic member, for manual operation.
